中文摘要：
在综合利用GPS与水准测量资料的基础上，针对面积较大或地形变化比较复杂的GPS测区，提出了分区拟合转换成正常高的方法。对各种常用拟合模型的适用性进行了分析，并提出了用双三次样条函数或者双三次曲面函数对拟合后的两个小区进行平滑连接，以及相应的算法和精度评定标准。实际算例验证了该方法的可行性，精度可满足四等水准测量的精度要求。
英文摘要：
Based on comprehensive utilization of GPS and leveling information, aiming at GPS in a large survey area with complex topography, the authors put forward a new method for subregional fitting and transforming GPS height into normal height, analyzed the applicability of the fitting models, proposed the method of using bicubic splines or bicubic surface function to carry out the smoothing junction for two fitted subregions, and presented corresponding algorithms and accuracy evaluation standards. It is verified that this smoothing method is feasible and its precision is four-grade leveling.
